When to work on baby # 2

Melissa

My daughter is 15 months old and I have been thinking seriously about trying for baby #2. So many pros and so many cons - my question is how do you make that decision?! I feel like it shouldn't be this hard but some days I am 100% for it and some days I think it's not the right timing and I should let my 1st be the baby a little longer and get used to parenthood a little more before I have another. I've always wanted my kids close in age but I don't know if I could handle 2 small children at 1 time. Advice?!
